Fails with IPython

[eulerfan271]

In an IPython (or Jupyter) console, imgcat errors and fails to load images, even when using kitty and explicitly setting the TERM environment variable to xterm-kitty. I'm not sure if this a bug report or feature request (or even a problem with Jupyter!), especially since the IPython/Jupyter console explicitly changes the TERM environment variable. I think this would be a useful feature/fix in any case, as an IPython provides many benefits over a python REPL.

Steps to reproduce:
-Start an IPython or Jupyter console using kitty (problem occurs with both python 3.6 and 3.8 for me)
-Explicitly change TERM value with %set_env TERM=xterm-kitty [or don't, doesn't make a difference in the outcome :)]
-Set matplotlib backend to imgcat, and plot something
-imgcat throws 'OutStream' object has no attribute 'buffer'

The module is working perfectly for me in kitty in a python REPL. Thanks for this great project!

Yes, I agree we need to detect ipython as a runtime and make the imgcat() function work properly. For now, you can use a ipython magic:

%load_ext imgcat
%imgcat (a python image object)
